i just began week three of the demo, so i'll make my remarks about the demo thus far (just past halfway):
The most obvious benefit i've noticed from INTRASTACK is the endurance boost. As i understood from the literature and bottle labels, the carnosine levels will buffer the acidity and keep muscles in optimal ph-levels so they can perform better. I feel the ability to finish the last reps in a tough set more so than before, when i was just taking whey and some simple carbs during my summer cut.
I forgot to take serious measurements at the beginning, so i'm going off eyeball judgments, but i feel some slight gains in size. i've managed to gain a pound or two, hopefully in lean mass. ill get a bodyfat and lean mass check from doug tomorrow.
i'm satisfied with this product and my training. I'll definitely look at it again once i try the xtend + vaso stack and burn through my protein- i might try just adding the intraxcell to keep carnosine levels up and replace the xtend with either whey alone or another bcaa+eaa supp.
SUMMARY:
taste definitely improved/ (or maybe i adjusted to it).
it mixes great, even better than my regular whey PWO shake.
great endurance boost, it holds true to its claims from what i can tell. hopefully ill be able to report bigger mass gains by the end of the month long demo.
